LT245/75R/16 BFG A/T Tires installed on stock '08 Liberty
 
Hey guys,

I wanted to make a thread about installing bigger tires on a Liberty without doing any lifts. This question comes up a lot, so I figured I'd make a thread about it, with lots of pictures.

Since installing these tires I have driven almost 10,000Km. There has been no rubbing anywhere. I did not have to pound the pinch weld. Any size larger than 245/75r/16 will require a lift.

Also posted the same thing on Lost forums

Feel free to ask any questions.

How bad did either size throw off ur speedometer? Has the bigger size messed with your ESC any? Thanks

I used a gps to determine the speedo difference. My speedo was bang on with my gps on stock tires. Both showed me traveling @ 100km/h.

But with these tires Jeep speedo is off by 4-5%.

I was traveling 100km/h according to Jeep's speedo, but gps was showing 104-105km/h.

I called dealership and they can fix this by changing the tire revolutions in the ecm, they charge half hour labor. They can only do this if the tire difference isn't very big, if the tires are even bigger then the reprogramming wont work.

I didn't bother with it, 4-5% isn't much.

And no affect on esc.

Good deal. Thats not bad at all on the speedo and great that it didn't screw with the traction stuff. Was kinda worried about that one. Thanks again. Oh and by the way the new treads look awesome on the libby!

No problems with ours either. Speedo is 2 mph at 70 mph. No big deal.

Very cool. A 255/70/r16 would be wider and shorter in diameter right? You think wider would be better for driving over sand?

255/70r/16 is ~5mm shorter than 245/75r/16 but 10mm wider. Difference of 9 Revolutions per mile.

Yes wider tire is better for driving over sand. More contact is better.
